Functionality Measures

• Desired end result rate (r) – essentially is matched to get

production preparing.

• Pattern time (CT) - maximum operation period

allowed each and every workstation (single w/s)

one particular

CT sama dengan r

exactly where

CT = cycle period

r sama dengan desired outcome rate (unit / hour)

Performance Steps

• Theoretical minimum volume of

workstation

ОЈt

TM =

CT

where

ОЈt sama dengan total period required to set up each device

(part or perhaps product)

CT = routine time

Overall performance Measures

• Line Performance and Stability Delay

Series Efficiency (%)

ОЈt

= (TM)(CT) x 100

Harmony delay (%) = 95 – (Line Efficiency)

wherever

ОЈt

sama dengan total period required to build each product

TM sama dengan theoretical bare minimum number of w/s

CT = cycle period

Performance Measures

• Nonproductive time

Nonproductive time = (TM times CT) – Σt

in which

TM = theoretical minimum number of workstation

CT = cycle time

ОЈt sama dengan total time required to put together each product (part or perhaps

product)
